ELS: {"message":"Smth went wrong","details":"(#_#) You can not register a new server! Right now you have 1 servers and your license limit is 1."}

Issue

During the CentOS ELS installation, the following error occurs:

$ sudo sh install-centos7-els-repo.sh --license-key CENTOS7-xxxxxxxxxxxxxxxxxxxxxxxx
[...]
{"message":"Smth went wrong","details":"(#_#) You can not register a new server! Right now you have 1 servers and your license limit is 1."}

Environment

• CentOS 7 ELS
• Plesk

Solution

1. Check `els-define`:

# yum info els-define
[...]
Error: No matching Packages to list

2. Check CLN (using the activation key or the server external IP). For an external IP, use one of the following:

# curl ifconfig.me

# curl ipinfo.io/ip

3. Remove the server from the CLN account, and re-register:

# wget https://repo.tuxcare.com/centos7-els/install-centos7-els-repo.sh
# sh install-centos7-els-repo.sh --license-key CENTOS7-xxxxxxxxxxxxxxxxxxxxxxxx

Cause

The ELS license not installed correctly.
